Properties of sound

Sound is a noise that travels into a persons ears. Property is something that belongs to a thing or a person.

One property of sound is that it sound gets weaker. This is proven because Mr Wong clapped on one side of the class room and the meter on the other side of the class room recorded a smaller amount of sound.

Another property of sound is that it sound travels the same in every direction. This is because Mr Wong clapped one meter in front, one meter back, one meter to the left and one meter above and the results were all the same.

The last property of sound is that sound can travel around corners. This is proven to be correct because Mr Wong went behind a wall and clapped and the meter picked up the sound.
